Los Angeles County sheriff's detectives are investigating the stabbing death of a man in Canyon Country as possibly gang related. Deputies from the Santa Clarita sheriff's station responding to a call Friday at about 10:45 p.m. found an unconscious man on the ground with several stab wounds to his chest. He was pronounced dead at the scene, on the 18100 block of Sundowner Way. His name has not been released. Anyone with information about the stabbing can call the sheriff's Homicide Bureau at (323)

Businesses have the tools and know-how to keep our personal information safe. They just don't do it. "It's expensive," said Nick Mancini, a partner at Tech Consultants, a Woodland Hills information technology firm. And that, in a nutshell, is why big companies that should know better routinely issue red-faced notices that they've been hacked and that customers' confidential info is on the loose. Target took it on the chin again Friday when it revealed that up to 110 million customers - not just the 40 million it originally reported - may have had their names, addresses, credit and debit card numbers and other information stolen.

The data breach at Target Corp. is dramatically larger than first estimated, affecting as many as 110 million consumers and deepening a public relations nightmare for the beleaguered retailer. The Minneapolis company said Friday that the personal information of as many as 70 million people - including names, addresses, emails and phone numbers - was stolen during the year-end holiday shopping season. That is in addition to the 40 million customers that Target originally said were hit by the cyberattack.

The track lighting has been installed, the pamphlets have been printed, and the 357-pound metal space rock that crashed to Earth 50,000 years ago has been bolted to its small display table. UCLA's Meteorite Gallery is officially open to the public. To the casual observer, this small room on the third floor of the Geology Building might resemble the trophy room of a fastidious rock collector. But to curator John Wasson, a 79-year-old cosmochemist at the Westwood campus, it is much, much more.

Assemblyman Mike Gatto and his family pleaded for the public's help Tuesday in the shooting death of their father, Joseph Gatto, a well-known artist and retired teacher found shot to death in his Silver Lake home. Flanked by Los Angeles Mayor Eric Garcetti, LAPD Chief Charlie Beck and other officials, the Gattos announced that the city had offered a $50,000 reward for information about their father's death. The L.A. City Council unanimously approved the reward Tuesday morning. “My father gave so much to our community,” Mike Gatto said.

Among the many stents, surgical clamps, pumps and other medical devices that have recently come before the Food and Drug Administration for clearance, none has excited the widespread hopes of physicians and researchers like a machine called the Illumina MiSeqDx. This compact DNA sequencer has the potential to change the way doctors care for patients by making personalized medicine a reality, experts say. "It's about time," said Michael Snyder, director of the Stanford Center for Genomics and Personalized Medicine.

A weakness in Snapchat's developer tools apparently has been discovered and published online. The vulnerability could allow hackers to find individual Snapchat users' information, whether or not those users keep their accounts private. Gibson Security, a collective of Australian hackers, published the vulnerability this week, claiming others can use an exploit called "find_friends" to try and match up phone numbers with Snapchat users. If there are any matches, the hacker will get the phone number's corresponding Snapchat username, display name and information about whether that account is public or private.

Can the eyes of photographed crime victims help authorities spot their victimizers? According to new research published Thursday in the journal PLOS One, high-resolution photographs can be "mined" for hidden information. Specifically, the authors said that photographs of faces can reveal enough visual information on bystanders to identify them. In a small sampling of 32 study participants, test subjects were able to spot familiar faces reflected in the pupils of someone who was photographed 84% of the time, researchers said.
